摘要
目的确定超临界CO2萃取栀子油的最佳工艺条件。方法采用超临界CO2萃取栀子油,用极差分析法确定其最佳工艺条件。结果栀子油最佳萃取得率12.00%。结论萃取压力是影响栀子油得率的主要因素;超临界CO2萃取栀子油的最佳工艺条件是:萃取压力25MPa;萃取温度45℃;解析釜Ⅰ压力12MPa;解析釜Ⅰ温度45℃。
Objective Decide the best condition of supercritical CO2 extraction technology. Methods： Supercritical CO2 extraction was used to extract oil from gardenia and the best qualification was decided by analysis of range. Results：Extraction yield of gardenia oil was 12%. Conclusions： Extraction pressure is the main factor affecting extraction yield. The best Extraction technology condition： pressure 25MPa; temperature 45℃ ; analysis caldron I pressure is 12MPa; analysis caldron I temperature is 45℃.
